Thanks Mike!
Do you have a link to a photo of the 'sunwrap' products that you
sell?
Yep, I need bi-focals - so the 'stick on' idea may be
just-the-thing!
I have found that in gliding we need a surprisingly small reading
'patch' - or else it interferes with our side-and-down view.
Cheers,
Jim

The Sunwraps(TM) are available in several varieties.
The most popular among pilots are the polarised blue blockers.
They have a
yellow/orange appearance.
Two sizes, normal and large.
The are made of polycarbonate so do scratch relatively easily the
polarisation doesn't seem to be extreme and they block most but
not all the
blue which lets your brain at least operate in colour not
monochrome.
I also have a pair of prescription Ol Eagle eyes that I am happy
with and
another pair of prescription sunglasses.
Polarised sunglasses may help by increasing contrast on LCD's (if
the LCD
is organised the right way!).
My Suntiger clip ons don't get used as I can't operate in
monochrome.
Fields of Salvation Jane don't show very well through Suntigers
but the
Sunwraps let through enough blue to still see blue and purple.
For those with prescription sunglasses who now need bifocals I
found a
product which sticks on to your existing glases to make them
bifocals.
Called stick on bifocals. Search for this on Google. They work
very well.
